Could you try if the patch from this PR solves your issue?
Thanks,

Please look at the " graph_traits_Dual_Arrangement_2.h " file, you will find that the CGAL::Arrangement_2 is used for calculations.
Maybe error is for that?

I was, by the way, able to compile the lines of code you have posted
after adding the appropriate include statements.

Exactly, compiler give error:

C2440: 'initializing': cannot convert from
'Arr_with_hist_2' to 'int'

(Notice that the error is not occur at runtime)

What makes you think that the Dual class does not

Thank you Efi,
But I don't want to delete CGAL::Dual because I
need to construct a dual graph representation of
the arrangement, and on the other hand I need to
have curve handler that it's possible with use
of Arrangement_with_history_2 class.
Apparently the Dual class does not accept
Arrangement_with_history_2 as input and
according to your answer I can't directly
convert Arrangement_with_history_2 to
Arrangement_2. I think, I must write my own dual
graph class that accept
Arrangement_with_history_2 as input.

Hi Morteza,
If you really need to convert
Arrangement_with_history_2 to Arrangement_2,
then you would need to reconstruct
Arrangement_2, but conceptually, everything
you can do with Arrangement_2 you can also
do with Arrangement_with_history_2.
Is it possible that you simply forgot to
include the header that contains the
definition of CGAL::Dual, namely,
<CGAL/graph_traits_Dual_Arrangement_2.h> ?
Anyway, if you still have a problem, please
paste a complete minimal program.
Efi

Hi, I want to use Dual class to

Arrangement_with_history_2 that I use to

I need to convert Arr_with_hist_2 to
